While architecting custom Android equipment the primary interesting point is which CPU to utilize. A CPU is the focal IC chip that controls an advanced item, in some cases alluded to as the ‘cerebrums’ of an item. Picking the CPU is the most major plan choice for your item on the grounds that the abilities and impediments of this IC predicate the capacities of the whole gadget.
Two CPU organizations that keep on overwhelming local China items are Mediatek (Taiwan) and Spreadtrum (China). While Qualcomm, around the world, is the main brand for top level cell phone CPUs, it’s more reasonable for high volume (100k+ units) purchaser gadgets than lower volume (10k+) custom gadgets. Planning telephones with Qualcomm CPUs requires all the more designing aptitude so advancement costs are higher. The presentation benefits that Qualcomm CPUs give are regularly pointless excess to what custom gadget clients need in any case.
Mediatek and Spreadtrum publicize various CPUs on their sites. Actually a couple of them are regularly utilized by major parts in Shenzhen’s assembling biological system, the world’s hotspot for tech equipment. The sites show a few more established and fresh out of the plastic new CPUs, neither of which are useful for custom items. More seasoned CPUs may before long get out of date and need execution. Spic and span CPUs are frequently too new for stable large scale manufacturing and their highlights are pointless excess for the necessities of most custom activities. The CPUs that have become famous picked up footing since they offer the best an incentive for the portion they serve.
(Generally) High End Segment 4G
Both Mediatek and Spreadtrum are demonstrating 5G chips on their site and a couple of huge (generally Chinese) cell phone brands have just delivered telephones utilizing CPUs from Mediatek’s 5G Dimensity line. At the point when new chips come out bigger brands which dependably sell high volumes are the first to advertise with items. It takes a ton of designing assets to build up an item utilizing another chip which is the reason CPU makers join forces with high volume brands to deliver the underlying items. When these brands have come out with items and the framework turns out to be more steady Shenzhen’s more modest improvement organizations begin delivering items for more modest brands.
Since 5G arrangements aren’t steady enough for more modest market marks yet they’re as yet not prepared for most custom ventures. Now 4G CPUs are as yet the most pragmatic for custom undertakings as the designers are most open to making items on these stages. Hence, in any event, for the very good quality portion, this article centers around 4G CPU choices.

This is Mediatek’s best in class 4G CPU. It offers elite for playing asset serious computer games and top of the line camera uphold. Mediatek depicts it like this:
“An updated octa-center CPU helps accelerates to 2.05GHz. Utilizing a blend of the most recent Arm Cortex-A76 and Cortex-A55 in mix with a huge L3 store, the G90 arrangement increments multi-strung execution up to 9%1 past direct contenders.
With speeds up to 800MHz, the most recent Arm Mali-G76 3EEMC4 GPU can play Fortnite and PUBG unbelievably easily, bursting through Manhattan benchmark up to 26%1 quicker versus direct contenders.
Up to 10GB of LPDDR4x at 2133MHz1 (4266MHz1 effective) provides generous bandwidth and memory capacity, while the latest UFS 2.1 storage yields ultra-fast data-streaming.”
The P70 replaces the successful P60 offering up to 13% faster performance and 35% lower power consumption. The chip includes an upgraded dedicated AI Processor Unit (APU) that provides up to 30% more processing efficiency than its predecessor. This chip is marketed towards gamers, camera enthusiasts, and advanced AI applications. Could be a good choice for custom products that need high performance onboard processing. Here’s what Mediatek has to say:
“The MediaTek Helio P70 incorporates a powerful Arm Cortex-A73/A53 octa-core CPU complex with an impressive Arm Mali-G72 class GPU. Versus the prior P60, the faster clock speeds generate up to 13% more performance. In-hand, there’s support for 20:9 displays at Full HD+ resolution that allow users to enjoy the most beautiful and modern smartphone designs with full fascia coverage.
MediaTek’s exclusive CorePilot 4.0 technology manages how tasks are assigned between processing resources, with a power management focus that’s on maintaining a sustainable, fast user experience through thermal management, UX monitoring and Energy Aware Scheduling (EAS+).”
This chip offers similar, but slightly reduced, features as the P70. It became mainstream in early 2020, about a year after the P70. Mediatek has this to say:
“The G70 incorporates a pair of powerful Arm Cortex-A75 CPUs operating up to 2GHz, plus six Cortex-A55 CPUs in a single, octa-core cluster. These are interlinked and share a large L3 cache for improved performance plus up to 8GB of fast LPDDR4X memory. For gaming, an efficient, high-performance Arm Mali-G52 class graphics processor operates up to a speedy 820MHz.
A multitude of hardware accelerators, such as a dedicated depth engine, Camera Control Unit (CCU), Electronic Image Stabilization (EIS) and Rolling Shutter Compensation (RSC) technology enhances video panning and ultra-fast recording (up to 240fps).
Ideal for popular AI-camera tasks such as object recognition (Google Lens), Smart Photo Album, scene detection and segmentation with background removal, and Bokeh-shot enhancements.
With MediaTek NeuroPilot support and full compliance with Android Neural Networks API (Android NNAPI), developers and device makers have the best possible ecosystem for Android enhancements and app development, with support for many common AI frameworks.”

Upper Mid Range 4G
These lower cost CPUs provide terrific performance for many dedicated single app custom Android products. The CPUs in this category provide an excellent balance of performance and features.
Mediatek P35 (MT6765) and P22 (MT6762)
These chips appear to use the same core, with key differences in display and camera resolution. The P35 supports display resolution up to 2400×1080, dual 13+13MP cameras, and a single 25MP camera. The P22 provides respectable, yet reduced, display resolution up to 1600×720, dual 13+8MP cameras, and a single 21MP camera. Both chips come with a suite of Mediatek technologies like CorePilot, Imagiq, MiraVision, NeuroPilot, Pump Express, Tiny Sensor Hub.
